Paul might continue to back controversial gun rights group

Collins complained about the group at a meeting of the Senate Republican Steering Committee last week.

She warned her colleagues that infighting among Republicans could give Democrats a good chance of capturing her seat in 2014, when she faces reelection, according to The New York Times, which reported on the private argument.

Paul, feeling attacked, stormed out of the meeting, according to The Times.

The senator on Wednesday said he does not plan to support primary challenges against any of his Republican Senate colleagues, although he might lend his support to primary challengers running for open seats.

“At this time I don’t have any plans to oppose any incumbent Republican,” Paul said.
